Last August Tendril, a US-based energy platform company, announced that they were opening their API’s and launching an energy application developer program. The idea is to allow developers to build on Tendril’s cloud platform and to deploy the developed applications on Tendril’s Tendril Connect cloud platform.

For developers this is an opportunity to develop applications addressing the energy challenge and have them deployed in a ready-made marketplace of up-to 70 million addressable households. Similar to the Apple App store, Tendril offers co-marketing opportunities for developed applications.

Tendril has also been promoting this initiative to developers by participating in Hackathons in San Francisco and more recently in New York. In conjunction with the New York Hackathon, Tendril ran a contest to see who could come up with the best apps using their API’s. The winner, eMotivator, won $3,000, while 2nd placed Green Carrot (screenshot above) won $2,000 from Tendril and another $1,000 from the Hackathon organisers for ?best user experience?.

Of course, if Tendril really want to talk to developers, they should also be attending our RedMonk Monki Gras conference in London next week (Feb 1-2)! I’m not sure what the collective noun for developers is (I asked on Twitter and received the following suggestions – batch? class? scrum? repository?), but whatever it is, there’ll be a shedload of them there!

One of the interesting things about the Tendril open API initiative is that it should stimulate lots of creativity in the Smart Grid space. So far, as Tendril CTO Kent Dickson noted in a call with me the other day, no-one knows what the Smart Grid killer app will be, but crowdsourcing the ideas is far more likely to lead to compelling results.
